とする電子制御サスペンシヨン装置。 In an electronically controlled suspension system equipped with an attitude control function that reduces roll displacement of the vehicle body by individually adjusting the fluid pressure in the fluid spring chambers provided in each of the left and right suspension units, the fluid spring chambers of the suspension units are An air supply control valve installed in the air supply path that sends fluid to the suspension unit, an exhaust control valve installed in the exhaust path that discharges fluid from the fluid spring chamber of the suspension unit, and the handle angular velocity are detected. a steering wheel angular velocity detection means,
A vehicle height sensor that detects the vehicle height, a vehicle speed-steering wheel angular velocity map with a control time set approximately corresponding to the lateral acceleration used for the vehicle body determined by the vehicle speed and steering wheel angular velocity, and a vehicle height displacement from left and right of the vehicle body. It has a vehicle height sensor map in which a control time is set approximately according to the lateral acceleration acting on the vehicle body, and when the steering wheel angular velocity detected by the steering wheel angular velocity detecting means is equal to or higher than a predetermined value, the vehicle speed - steering wheel angular velocity is determined. The control time given by the map is calculated, and if the steering wheel angular velocity detected by the steering wheel angular velocity detecting means is less than a predetermined value, the control time given by the vehicle height sensor map is determined based on the vehicle height data output from the vehicle height sensor for a set time or more. 1. An electronically controlled suspension system comprising: a controller for controlling the roll of a vehicle body by controlling the opening and closing of the air supply control valve and the exhaust control valve in accordance with the control time required to control the air supply control valve and the exhaust control valve.
